Morgan Building, Historic office building in downtown Portland, United States

The Morgan Building is an office structure in downtown Portland built in the early 20th century, displaying Beaux-Arts architectural style. It features elaborate decorative elements and solid construction typical of that commercial design period.

The building was designed by the architectural firm Doyle & Patterson and is listed on the National Register of Historic Places. It was completed during Portland's expansion as a major West Coast commercial hub.

Theodore Kruse opened the Rainbow Grill here in October 1913, after closing his Louvre restaurant, a gay-community gathering spot caught up in the 1912 Portland vice scandal. The grill advertised "fat, juicy, delicious" oysters and a "Special Men's Grill" where diners chose their meat; it closed in June 1915. Restaurants Hunan, Nodoguro, Roe and Tercet have since operated in the building.

The structure sits near multiple public transit stops and is easy to reach by bus or car. The surroundings are lively during business hours with many dining and shopping options nearby.
